COLUMBUS, Ohio —  Ohio's attorney general has resigned amid the scandal of a sexual harassment investigation in his office and his extramarital affair.

Marc Dann has been under pressure of possible impeachment and announced he was stepping down on Wednesday.

The 46-year-old Democrat at first refused to resign, despite demands by Democratic Gov. Ted Strickland and others within his party.

Dann admitted May 2 to an extramarital affair with an employee that he said contributed to an atmosphere leading to sexual harassment claims against a top aide. Three aides were forced out in the harassment investigation, which showed managers encouraged a casual work environment with frequent profanity and inappropriate interactions with subordinates.
